major branche merging salsa/mpfr with trunk

812c0369 11/22/2015 12:05 AM Xavier Thirioux

corrected pessimistic behavior of optimization phase -O 3

e24b2e9b 04/13/2015 10:08 AM Xavier Thirioux

some optimization in code optimization !!

5f31b494 04/09/2015 10:57 PM Xavier Thirioux

corrected a bug when activating optimization (-O 3) (edge missing in a dep graph)

307aba8d 09/26/2014 05:52 PM Xavier Thirioux

- changed the basic optimization scheme (option -O 2), which unfolds
local variables and global variables that are either cheap to evaluate
or used no more than once.

67896f6d 09/24/2014 12:13 PM Xavier Thirioux

- corrected a bug in optimizating mode (option -O 3)
- changed the printing of unused variables

d5fe9ac9 09/18/2014 05:25 PM Xavier Thirioux

- corrected bug in node reset clock
- cleaner (but heavier !) code generation scheme for automata

70e1006b 09/02/2014 02:43 PM Xavier Thirioux

This is a major revision:
- added interface files (.lusi) in the language, that can be compiled on their own, giving an object file (.lusic) and a header file (.h)
- modular code generation, from Lustre to C level included.
- nice amount of code refactoring

7dedc5f0 07/15/2014 02:15 PM Xavier Thirioux

added some functions, prior to code refactoring

084c1ce4 07/12/2014 02:23 PM Xavier Thirioux

- reimplementation of the reuse algorithm (option -O 3),
much more simple and efficient.

01f1a1f4 07/10/2014 12:49 PM Xavier Thirioux

- added missing constraint check when sub-clocking
tuple expressions
- added an algorithm that reuses dead or clock-disjoint
variables instead of declaring/using new ones.
- NOT carefully tested. Use option -O 3 if you want
to give it a try...

b38ffff3 07/09/2014 09:57 AM Pierre-Loïc Garoche

Updated the licence info and header for each file.
Moved backends in separate folders

2cf39a8e 07/08/2014 04:53 PM Xavier Thirioux

- many bugs/limitations in lifting operators to tuples have been worked out:
- typing/clock calculus/normalization now work properly
- still, a bug in annot generation (this one is for Ploc !!)
in file normalization, line 396
- bug corrected in subtyping...

34a5a072 07/07/2014 10:35 AM Xavier Thirioux

work in progress in liveness analysis...

7cd31331 07/04/2014 04:57 PM Xavier Thirioux

work in progress (code optimization again)

1837ce98 07/03/2014 10:40 PM Xavier Thirioux

added some infrastructure to ease optimization (reusing vars)

0038002e 07/02/2014 05:29 PM Pierre-Loïc Garoche

Prepared first stage of code reorg:
1. moved type def in
2. moved constructor and basic functions in corelang
3. Modified eexpr with prenext quantifiers

d96d54ac 06/27/2014 04:29 PM Xavier Thirioux

added construction of a fanin table for local variables of a node.
could be useful for a finer variable elimination scheme at the Lustre level.
to be continued...

9aaee7f9 06/26/2014 04:48 PM Xavier Thirioux

added warnings for useless variables (at verbose level 1)
- exact definition of 'useless' may be further refined
- display could certainly be improved

e8c0f452 03/20/2014 03:41 PM Xavier Thirioux

liveness analysis improved. BUG found in causality wrt clocks...

3c48346d 03/19/2014 11:00 PM Xavier Thirioux

- modified example (arguments are now in the right order wrt clock declaration).
- debugged liveness analysis...

d4101ea0 03/19/2014 06:08 PM Xavier Thirioux

- reimplemented computation of dead variables
- added computation of a reuse policy (depending on types)
- not yet used though, would have to change code generation
in order to be useful...
